This story is interesting.  I wonder how they got the source material?
Would Glenn Gould have cut rolls, or are these transcribed somehow from
audio recordings?  This deserves some more details!

 [ "The music will be played on a grand piano that has been specially
 [ programmed to give a note-perfect, live rendition of ancient
 [ recordings made by Alfred Cortot in 1928 and Glenn Gould in 1962.
 [ "... It has successfully tried out the Cortot and Gould pieces on
 [ the Disklavier Pro, one of only a few concert grand pianos that
 [ can record and play back high-definition MIDI files."
